The virtual rack; effect selection. VCM effects.
As an alternative to the varied SPX multi-effects available there are six VCM (Virtual Circuit Modelling) effects.
These VCM effects give M7CL users access to some sounds only previously available from rare, fragile, analogue
equipment or other higher cost live Yamaha mixers like PM5D V2.
Every channel on M7CL has EQ and a compressor included, but the VCM effects provide an alternative style. How-
ever VCM technology is extremely demanding of DSP resources so only one stereo or dual mono unit can be created
from each M7CL effects engine.
N oott e e; In the default, the effects engines are patched as send and return effects so we suggest re-patching the VCM

effects as inserts. Tiipp; Try Open Deck inserted on your masters to add analogue quality to your mix.
Comp 276. These models recreate the fast
response, frequency characteristics, and
tube-amp saturation of the most in-demand
analog compressors for studio use, delivering
classic-style compression with all the punch
and fatness you'd expect from a fine piece of
studio-grade analog gear.
Comp 260. Featuring faithful modelling of
the solid-state VCA and RMS level detection
circuitry of the late 70's, these Add-on Ef-
fects bring back the sound of classic comp/
limiters used primarily for live sound rein-
forcement applications.
The 601 equalizer offers two equalizer types
– Clean and Drive. The Drive type models the
distortion characteristics of 70's analog EQ
circuitry, delivering musical-sounding drive
and saturation. The 601 is a stereo sixband
parametric, and it accurately reproduces
both the boost and cut frequency response
and band interaction of vintage analog gear.
Open Deck recreates both the analog circuit-
ry and tape characteristics that shaped the
sound of openreel tape recorders. Because
of their ability to smooth out peak levels and
tidy up the response, many high-end record-
ing studios still maintain open-reel recorders
to be used to provide tape compression at
the mastering stage.
Different types of tape; new, old, etc. are
also selected and used according to the
unique sounds they produce.
The Open Deck provides models of four ma-
chine types: Swiss '70,Swiss '78, Swiss '85,
and America '70. You can even combine dif-
ferent record and playback decks for a wider
range of variation.
VCM is a technology developed to use traditional
DSP processing power in a revolutionary new way to
recreate the circuits of traditional analogue audio
devices. Pioneered by Yamaha's K's Lab it was
originally used to recreate the sounds of analogue
synths, but the techniques were soon adapted to
make models of analogue devices like Compressors
and EQs. Until the M7CL V3 upgrade this technology
was only available on Yamaha's higher end products
or at extra cost.

For engineers requiring an even broader range
of processing choice, you can access Waves
SoundGrid effects running on an external
PC/Mac server via a special Mini YGDAI card
made and distributed by Waves. This system
is very low latency and can offer redundancy
to provide excellent characteristics for live
mixing use.
